PowerShell/SCSM - Get Manual Activities Completed in the last month

I got an interested question from a reader that asked how he could get all the Manual Activities completed in the last 30 days using one Filter.

I got some trouble working with Get-SCSMObject and multiple conditions in the -Filter parameter, but got it working using the -Criteria parameter. Hope this help!

# Import Smlets Module
Import-module -name Smlets

# Get the Manual Activity Class
$MAClass = Get-SCSMClass -Name System.WorkItem.Activity.ManualActivity$

# Get the Manual Activity Completed Status Enumeration
$MAStatusCompleted = Get-SCSMEnumeration -Name ActivityStatusEnum.Completed$

# Get the starting date from where we are searching
$MAModifiedDay = (Get-date).Adddays(-30)

# Get the Criteria Class
$CriteriaClass = "Microsoft.EnterpriseManagement.Common.EnterpriseManagementObjectCriteria"

# Define the Filter
$Filter = "Status = '$($MAStatusCompleted.Id)' AND LastModified > '$MAModifiedDay'"

# Create de Criteria Object
$CriteriaObject = new-object $CriteriaClass $Filter, $MAClass

# Search for Manual Activities
Get-SCSMObject -criteria $CriteriaObject
